What is energy expenditure?
Energy expenditure is that amount of calories that someone uses in one day by exercising or doing everyday tasks.
What causes positive energy balance and what are the effects of positive energy balance?
Positive energy balance is when energy intake exceeds expenditure weight is gained
Why is net energy expenditure more important than gross energy expenditure?
Because it is the actual amount of calories expended. NEE = GEE (Gross Energy Expenditure) - REE (Resting Energy Expenditure). Source: My B.S. in Exercise Science/Kinesiology
How much energy does it take to lose a lb?
3500 Calories.....A Calorie is simply a measurement of energy expenditure
What does energy balance mean?
There are several different energy equations. For kinetic energy: KE=1/2mv2 For gravitational Potential energy: PE=mgh For rest potential energy: E0=mc2 m=mass, v=velocity, g=9.80m/s2 (acceleration of gravity on Earth) , h=height, c=2.998*108m/s (The speed of light in a vacuum)
How does temperature affects the body?
For mammals very little, except for the energy expenditure required to maintain a constant internal temperature.
How does age affect energy balance?
Age can affect energy balance in several ways. As individuals age, their metabolism naturally slows down, resulting in a decrease in energy expenditure. Additionally, muscle mass tends to decrease with age, which further decreases the amount of calories burned at rest. Age-related factors, such as hormonal changes and a decrease in physical activity, can also contribute to a shift in energy balance.
Does increasing muscle mass increase energy expenditure?
Yes. For one thing, increasing any kind of mass increases energy expenditure-- yup, it takes more calories for a 200 pound person to climb the stairs than for a 100 pound person. Additionally, muscle mass maintains tone, which is constantly using up calories, as if you were constantly half-flexing.
Where are most of the calories in your food burned?
Most of the calories consumed through food are burned through your Basic Metabolic Rate. This is the energy required by your body to simply stay alive, and accounts for between 50% and 80% of the bodies total energy expenditure.
What is the Difference between positive and negative energy balance in relation to food and exercise?
A positive energy balance is when you're taking in the correct amount of calories according to your age, height and gender and expending the appropriate number of calories. A negative balance is when you're not. I know which school you're from, I had to do this as an assignment too...
How do hogs fatten?
They are fed lots of food more calories in means fatter animals. It is also possible to reduce their energy expenditure by restricting their movements, for example by keeping them in small spaces. It is also possible to reduce their energy expenditure by keeping them warm for example in a heated indoor enclosure.
What is body energy balance and what happens if the balance is not precise?
It is the balance between nutrients provided to the body and energy spenditure. If nutrients create more calories of what you burn, fats are stored and at some time obesity will appear. If you burn more calories of what you get in nutrients, loss of fats and muscle will happen until malnutrition disorders surge.
